Description

Bamboo carbonized wood manufacturing method and bamboo carbonized wood The present invention relates to a method for manufacturing carbonized bamboo wood and the carbonized bamboo wood, and more specifically, to a method for manufacturing natural carbonized bamboo wood using Mao bamboo and the carbonized bamboo wood. First, if we look at the prior art, Wood is commonly used as a material that serves both as a finish and decoration for the interior and exterior surfaces of structural elements that constitute the space of a building. Recently, with the growing interest in interior design and nature-friendly living environments, the demand for eco-friendly wood is rapidly increasing. Therefore, solid wood or plywood panels with veneer that can produce the same atmosphere as solid wood are widely used. Among natural woods, bamboo is known to be very hard, sturdy, and have excellent moisture resistance. By utilizing these excellent properties of bamboo, it can replace expensive lumber such as solid wood. In other words, bamboo boards are economical, generate a small amount of negative ions which are effective for health promotion, and have high thermal conductivity, making them advantageous for keeping warm against the cold and heat. Above all, it is known to have a forest bathing effect by generating fine sap even when UV-coated. However, bamboo has the disadvantage of easily discoloring due to ultraviolet rays because its surface is bright, so it is carbonized for use, and various methods for this are being proposed. For example, Korean Published Patent Application No. 10-2009-0090580, "Bamboo Flooring and Method of Manufacturing the Same," is proposed; as another example, Korean Registered Patent Application No. 10-0698515, "Method of Manufacturing a Bamboo Board," is proposed; and as yet another example, Korean Registered Patent Application No. 10-1347782, "Method of Manufacturing a Bamboo Panel for Architectural Interior Materials and a Bamboo Panel for Architectural Interior Materials Manufactured Using the Same," is proposed. In other words, development is intensifying to manufacture boards that can maximize the advantages while compensating for the disadvantages of bamboo through multiple processes such as cutting, aging, drying, carbonization, and pressing, following the cutting of bamboo into a certain width and length. However, since most of these processes must be performed manually by using commercially available devices or simply modifying them, there is a problem where productivity and quality are significantly reduced. In addition, if the stacking amount is not accurately supplied during the process of compressing bamboo into boards, the thickness and strength decrease, which ultimately leads to reduced productivity and wasted labor. In addition, although the ‘carbonized board having a wood grain and method of manufacturing the same’ of Patent No. 10-1036289 and the ‘method of manufacturing a high-density carbonized board’ of Patent No. 10-1374599 have been disclosed, the aforementioned problems are still not being improved. FIG. 1 is a flowchart showing a preferred embodiment of the present invention FIG. 2 is a test report verified through the present invention. Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be explained with reference to FIGS. 1 and FIGS. 2 as follows. First of all, the method for manufacturing carbonized bamboo wood according to the present invention is, A manufacturing method for producing a natural carbonized board using bamboo comprises: a cutting step (100) for cutting bamboo to a length of 2250 mm, a width of 15 mm to 25 mm, and a thickness of 2 mm to 4 mm; a pest control step (200) for removing starch, sugar, and insects from the cut bamboo; a drying step (300) for placing the pest-controlled bamboo into a drying kiln and drying it; a carbonization step (400) for carbonizing the dried bamboo; a re-drying step (500) for carbonizing the bamboo until the moisture content of the bamboo reaches 8 to 15%; an adhesive step (600) for placing the re-dried bamboo into a housing equipped with an adhesive (phenol); a compression step (700) for compressing the adhesive-completed bamboo; a sanding step (900) for sanding the compressed bamboo according to the user's choice; a sterilization step (1000) for spraying a disinfectant on the surface of the sanded bamboo and drying it; and sterilization The process consists of a finishing step (1100) in which wood oil (WOCA) is applied to the finished bamboo to complete it. In addition, the carbonized bamboo wood of the present invention is manufactured by the above-described manufacturing method. To explain the present invention described above in more detail, First, the present invention is a technology that supplements the technology of the applicant’s registered patent No. 10-1432229, "processing line device for natural carbonized
